Environment and Microbes

Microbial Bioremediation, Biomining, and Microbially Enhanced Oil Recovery (MEOR)
  • Sanjai Saxena


Fundamentally, microbes play a vital role in global recycling of matter in order to obtain energy and grow, thereby releasing carbon, nitrogen, phosphorus and sulphur. The microbial buffet comprises diverse form of materials like dead plants and animals, wastes from human and animals and food leftovers. These interactions of microbes help in nutrient recycling and are referred as biogeochemical cycles. Microbes have been found to be surviving in extreme environmental conditions which at times are extremely difficult for survival of other life forms including human beings. The metabolic versatility of these microorganisms not only helps in removing harmful wastes from the environment but also propels recovery of important products during geological explorations. In this chapter we explore the role of microbes in degradation of xenobiotics and petrochemicals, in wastewater treatment, in recovery of minerals and crude oil and finally bio-concentration of toxic heavy metals from the environment. The chapter also dwells upon harnessing the microbial potential in recovery of petrochemical resources and important elements from the earth’s crust.
